,5 Referring now in detail to the drawings, 10

designates a lock embodying the invention, adapted to be attached to a door adjacent the edge thereof, and 11 designates a keeper for the lock adapted to be attached to a door jamb. The lock 0 10 comprises a casing 12 having a front wall 13, top and bottom walls 14 and 15, an end wall 16 remote from the door edge, and an end wall 1'7 adjacent the edge of the door and provided with an opening 18 for slidably receiving a portion of 5 the horizontal bolt 25, as will appear hereinafter.

The rear of the casing may be closed by a cover plate 26 resting on aledge formed around the rear edge of the casing and screwed thereto by means of a screw 21. The inner surface of said front wall 13 is formed with a pair of parallel e0 guide walls 23 and 24 and slidably mounted between said guide walls is the horizontal bolt 25 shown in detail in Figs. 5 and 6 and provided with a central wall portion 26 slidably contacting said front wall 13.

Extending from said wall portion 26 toward the end wall 16, are a pair of aligned, flat arms 27 and 28; and projecting rearwardly from said portion 26 is a transverse wall 29. Adjacent said wall 29 the arms 27 and 28 are provided with 70 aligned ledges 30 and 31. Adjacent the outer end thereof, said arm 28 is formed with a ledge 32 on the same level as the ledges 30 and 31 and with a rearwardly projecting wall 33. The arm 27 is preferably somewhat longer than the arm 75 28 and is likewise provided with a ledge 34 on the same level as the ledges 30, 31 and 32, and with a rearwardly projecting wall 35 having a slot 36 on the inner end edge thereof.

For the purpose hereinafter appearing, said so rearwardly projecting wall 29 is provided with a pair of spaced symmetrically disposed projections or pins 37. Extending from said portion26 of the horizontal bolt and projecting toward the wall 17 of the casing, is a bolt portion 40 adapted to 35 project through said opening 18, and forming with said portion 26, a shoulder 42 adapted to contact said wall 1'7 to limit the projecting movement of said horizontal bolt. Said horizontalbolt is further provided with a wall portion 45 extend- 9!) ing rearwardly from one end of the wall portion 40, and a middle portion 46 extending from said Wall 45 toward said wall 29. On opposite sides of said central portion 46, said horizontal bolt is provided with parallel rack portions 47, for the purpose hereinafter appearing.

For projecting said horizontal bolt, there is provided a T shaped member 50 having a fiat wall portion 50a slidably mounted on the ledges S0, 31,

32 and 34, and a rearwardly projecting wall 51 contacting said wall 29. Said portion 500' is further provided with rear edges 52 and 53 adapted to slidably contact the walls 33 and 35 of said arms 28 and 27 respectively. Fixed to said portion 50a is a tube 54 having a through opening 55 and a semi-cylindrical portion 56 projecting rearwardly toward said cover plate 20. A pin 55a having a head 56c, may also be fixed to wall portion 50a and adjacent said wall portion 51.

Rotatably mounted on said front wall 13 is a hand knob 58 to the inner end of which there is fixed an arm 59 provided with a pin 60 journaled within said opening 55.

It will now be noted that as the hand knob 58 is rotated, the member will be caused to slidably move transversely of the longitudinal mid-section of the horizontal bolt 26, and said horizontal bolt may thus be moved longitudinally. A spring 62 having a central coiled portion 63. disposed about the pin a is provided with arms 66 and 67, the former contacting the front surface of wall 50a and extending into said slot 36 of the wall 35 and the latter arm contacting the wall 29. Said spring 62 serves to normally retain the horizontal bolt in fully retracted and fully projected positions, as shown in Figs. 1 and 2 respectively, of the drawings and further serves to retain member 50 from lifting off said ledges 30, 31, 32, 35.

The top and. bottom walls 14 and 15 of the casing are preferably provided with aligned tubular portions 14a and 15a adjacent the end wall 1'7 and slidably mounted within said tubular portions are a pair of similar, symmetrically disposed vertical bolts 70, described and shown in detail in our said co-pending application, and each comprising a part '71 slidably mounted in one of said openings, and a U-shaped member '72 rotatably mounted on said member 71.

The tubular openings 14a and 150 are preferably square in cross-section, and the members '72 preferably each comprise an arm '74 of square cross-section, from which there extends a cylindrical portion '76 at the outer end of which there is formed a pinion '7'7. Extending from said arm '74 is a portion '75 likewise of square cross-section, and adapted to extend beyond the edge of the door. An arm '73 preferably of square crosssection extends from said portion '75 and is disposed parallel to said arm '74. The member '71 is provided with a cylindrical opening receiving said cylindrical portion '75, and is further provided with a slot '78 receiving a pin '79 fixed to and projecting from said cylindrical portion '76 to prevent relative sliding movement between said members '71 and 72, and to limit rotation of said member '72 to 180 from the position shown in Fig. 1 to that of Fig. 2. Fixed to the inner ends of said members '71 are rearwardly projecting pins 80, for the purpose hereinafter appearing. The front side of each member '71 is cut away as at 71a to expose the gear 7'7, and permit the same to mesh with one of the rack portions 4'7 or 48 as shown in Fig. 4.

The rear cover plate 20 is provided, for the purpose hereinafter appearing, with a pair of symmetrically disposed openings 82, and lying against the inner surface of said rear cover plate are a pair of similar, symmetrically disposed flat bolt actuating plates 83 having pins 84 at adjacent ends journaled within said openings 82. Said plates 83 are provided with slots 85 each receiving one of said pins 3'7 therethrough. Adjacent the outer ends thereof, said plates 83 are formed with small slots 8'7 receiving said pins 80. With the lock in position shown in Fig. 2, and the horizontal bolt projected, and the vertical bolts retracted into engagement with the keeper 11, as will appear hereinafter, the actuating plates 83 will be pivoted inwardly substantially into contact with one another. In such position the portions '73 of the bolt members 72 will be received within the tubular openings 14a and 15a. and the pinions '1'? will substantially contact one another.

For the purpose hereinafter appearing, the slot 85 in each plate has a portion extending radially toward one of the pins 84 and with a portion 91 inclined outwardly away from the midsection of the casing and toward the end wall 1'7. At the end of said portion 91, said slot 85 has another radially extending slot end portion 92. At the inner end of the slot portion 90 there is a slot portion 94 inclined away from the horizontal mid-section of the casing and toward the end wall 16, said slot portion 94 terminating in a short, radially extending slot end portion 95.

The operation of the lock 10 will now be described. Beginning with the parts in unlocked position, as shown in Fig. 1, it will be noted that the pins 3'7 are at the extreme left ends of the slots 65 and within the portions 95 of said slots. As shown in Fig. 1, further, the inner ends of the portions '73 of the bolt members '72 project within the tubular openings 14a and 1571 so that no rotation of said parts 72 is possible in the position of said figure. Further, the rack portions 4'7 are disposed to the left of and are out of mesh with the pinions or gears 7'7, which are disposed somewhat closer to the mid-section of the casing than said rack portions. Further, as shown in Fig. 1, the bolt parts '72 project inwardly of the end wall 1'7 so as not to project beyond the edge of thedoor.

Upon rotating the knob 58 for projecting the horizontal bolt 25 in a clockwise direction, looking at Fig. 1, the member 50 will be reciprocated between the walls 33, 35 and 29 of said horizontal bolt, and the bolt will begin to move toward the riwt. During the first part of the movement, the pins 3''! will move within the radially extending portions 95 of the slots, without pivotal movement of the plates 83 or bolts '70.

Further projecting movement of the horizontal bolt will bring the pins 3'7 within the slot portions 94. During this part of the movement the plates 83 will pivotally move about said pins 37 away from each other, and away from the horizontal mid-section of the casing. Due to the engagement of said plates 83 with the pins 80, the bolts '70 will be moved a short distance 128 away from each other sufliciently to bring the inner ends of the arms '74 somewhat beyond the ends of the tubular portions 14a and 15a. This movement will bring the gears '77 in alignment with the rack portions 4'7 and substantially in mesh therewith. Continued movement oi the horizontal bolt to the right, will bring the pins 3'7 within the slot portions 90, said slot portions then being disposed parallel to each other and extending radially toward the pivot pins 84.130 During this part of the movement, the plates 83 will not be rotated, but the racks 4'7 will engage the pinions '77 for rotating the members '72 about the axis of portions '76 to project said members beyond the edge of the door.

Further movement of the horizontal bolt will bring the pins 37 within the slot portions 91 for causing the plates 83 to be pivotally moved inwardly toward each other for moving arms '73 into engagement with the keeper 11. During 14G this last movement, the pinlons will be out of mesh with the racks 47. Further movement of the horizontal bolt will bring the pins 3'7 within the radial slot portions 92 for further projecting the horizontal bolt without affecting the vertical lit bolts.

As shown in Fig. 1, when the horizontal bolt is fully retracted, the pins 37 are within the slot portions 95 andare horizontally disposed. In this position, movement of the vertical bolts 13 either outwardly or inwardly is prevented. Also in the position of the parts as shown in Fig. 2 of the drawings, with the horizontal bolt fully projected, the pins 3'1 are in the slot portions 92 which are likewise horizontally disposed so as to prevent outward or inward movement of the vertical bolts.

It will be further noted that in the beginning and ends of the strokes, the square shaped arms 74 of the U-shaped bolts are received within the tubular square openings 14a. and 15:: so as to prevent rotation of the bolt parts 72. In other words, beginning with the lock in the position shown in Fig. 1, the U-ehaped vertical bolts must be first moved outwardly before the bolt parts 72 can be rotated. A positive acting jimmy-proof lock is thus produced.

For the purpose hereinafter appearing, the portions 50a of the member 50 is formed at one corner thereof with a beveled or inclined edge 57, and the upper wall 14 of the casing is provided with an inwardly extending projection 57a adapted to contact said edge 57 in the projected position of the horizontal bolt. With this construction, should the knob 58 be broken and the arm 59 removed, the horizontal bolt nevertheless could not be pushed back to retracted position, thus providing additional safety for the lock. The lug or projection 57a on the casing contacting the member 50, prevents retraction of the horizontal bolt without actuation of the hand knob or key. Obviously, in rotating the hand knob to retract the horizontal bolt from projected position, the member 50 will slidably move with respect to the horizontal bolt so as to clear the lug 57a.

Preferably the upper and lower edges of the end wall 17 are grooved, as at 101, for receiving sides a of the bolt portions 75.

The strike 11 may comprise a wall 102 provided with an opening 103 for receiving one end 45 of said horizontal bolt 25, the upper and lower edges of said wall 102 being formed with grooves 105 for likewise receiving the inner sides 75a of said portions '75. Extending from the wall 102 is a wall 104 adapted to be attached to the door jamb by screws, or in any other suitable manner. Extending from the upper and lower ends of said wall 104 are walls 107 provided with square openings 108 for receiving the arms 73. Preferably, the inner surface 110 of said wall 102 is provided with recesses 111 adjacent the upper and lower ends thereof for receiving the inner sides 112 of said arms '73.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
